that are used on moving objects, such asvehicles, automobiles, j locomotives, boats, etc.

The object of my invention is to provide a cheap, simple and eflicient device for operating lights, such as incandescent lights, so

that such lights can be shifted to different angles, as desired, and for diflerent purposes, at the will. of the operator, while at the same time such light can be maintained in the position as set and. will not be required to be held by the operation in its set position.

To these ends my invention consists, generally stated, in the novel arrangement, construction and combination of parts as hereinafter more specifically set forth and described and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use my improved operating devices for lights, I will describe the same more fully referring to the accompanying drawings, in which Figure 1 is a side elevation partly in section of my improved operating device for lights showing the lamp in its normal or straight line position. Fig. l is a detailed View of another form of operatingrod. Fig. 2 is a sectional View showing the lamp in the same position with the dotted lines showing another position. Fig. 3 is a perspective View of one of the members of the ball and socket joint shown in Fig. 1. Fig. 4 is a front View of the lamp. Fig. 5 is a sectional view partly in full lines showing the device for operating two lamps. Fig. 6 is an elevation partly in section of one of the lamps shown in Fig. 5. Fig. 7 is a plan view of the connecting gear shown in Fig. 5. Figs. 8 and 9 are sectional views of the gears shown in Fig. 7. Fig. 10 is a view showing another form. of connecting two lamps, with onelamp shown in full lines'and the other in section. Fig. 11 is a vertical section of one of the lamps shown in Fig. 10.

Like symbols herein indicate like parts in each of the figures of the drawings.

As illustrated in the drawing my invention is shown and will be described in connection with its use on an automobile, although --it will be evident that it can be used onv other moving objects or vehicles, and as shown in Fig. l a single lamp A is applied to and supported centrally by the radiator front a of the automobile and at the top. of the same. The lamp A is provided with the annular inclosing casing 1, which is secured to the supporting front a in any suitable manner, such as through the flange 2 on the inner end of said casing by bolts or screws 3, and at the outer end of said casing is the lens or glass 4, which is connected or supported in front of said casing, as hereinafter described, and is of hollow or globular shape to permit the movement of the parts of the lamp within the same, as hereinafter described.

lVithin the casing l and extending back from the same and front a is the annular supporting member 6 for the lamp A and operating devices for such lamp, as hereinafter described, and such member is provided with the hollow extension 7 for such devices and ring'or collar 8. lhis ring or collar 8 fits within the casing 1 by being secured to the front a through its flange 8, and its outer'end is provided with a flange 9, which fits against a flange 4 on the lens or glass 4 for holding said glass in position in the casing, with such flange l being held thereby against a flange l on the outer end of said casing,

lVithin the front of the member 6 is the annular tilting member 10, which is of 'curvedshape and is pivoted on each side to the member 6, as at 11. "Within the tilting member 10 is the reflector plate 12, which is of the usual vconcavo-conveX shape and secured at its outer edge to the tilting support 13. This tilting support 13, which is of bowl-shape surrounds the reflector plate 12, and is pivoted to the tilting member 10 by the pivots 1 f diametrically opposite each other and at an angle of ninety degrees (90) to the pivots 1.1. The tilting reflector support 13 is secured centrally to and around a lamp socket 15 which extends through the reflector plate 12.for the usual electric lamp bulb 16 to be connected thereto, and the usual wire connections 17 are made to said socket from any suitable source of supply. A bracket 18 is connected to the rear of the socket 15 and extending back from the same is a bar 19 having a ball 20, which is adapted to fit within the hollow portion 21 of a lever 21 and engage with a rounded portion 22 at the open front end of said hollow portion, said lever being slotted as shown at 20 in Fig. 3. Extending back from the rear end 7 of the extension 7 is a bearing 23 which has an operating rod 24: mounted within the same, and at the front end of said rod and within said extensionsis a '-V-shaped arm 25 to which is pivoted the rear end of the lever 21 by a bearing 21 on said lever fitting around the free angle portion 25 on said arm, while a spring 26 fits within the hollow portion 21 on said lever and bears against the ball 20 to hold said ball in engagement with the rounded portion 22 on said lever. The rear end of the rod 24 is provided with a circular handle 27 for turning and moving said rod longitudinally, which handle is removably secured to said rod, and has an arm or pro-- jecting portion 28 extending out therefrom to assist in turning the handle. I

The use and operation of my improved operating device for lights is as follows When the device is used in connecion with automobile lights, and where the light is placed centrally of the radiator front, as

shown and described, the operating rod 24 can extend through the radiator and under the hood to a position where the handle 27 on such rod can be positioned in front of the dash and within easy position and reachof the driver or operator on the automobile. In the osition as shown in Figs. 1 and 2 the lamp is placed for going straight ahead, and the member 10, support 13,v reflector 12,

land light 16 are in the position thus shown in said figures, while the rod 24, arm 27 and rod 21 are in their rearward or normal positions. When it is desired to shift such lamp A to throw the light 16 to either side or up or down positions, the operator pushes forward the rod 24: by the handle 27 to the position shown by dotted lines in Fig. 2, and

upon turning said rod by said handle will throw or shift the member 10, tilting support 13, reflector plate 12 and light 16 of the lamp to either of the positions named above, as desired, through the medium of the ball connection 20, lever 21 and arm 25, and each of such positions will be indicated and be regulated by the position of the arm 28 on the handle 27. It will be evident that when the lever 27 is thus thrown to its extreme forward position that the greatest angle of the lamp A will be obtained in any of its shifted positions, and the casing 1 and supporting member 6 have their two sides cut away as at 6, in order to allow the light 16 from such lamp to obtain its greatest amount of throw to either side, while the throw of the lamp can also be made in lesser angles by diiferent positions of the rod 24 and lever 21 intermediate of those shown, and during all these positions of the lamp, the deflector 12 and its support 13 can swing on the member 10 by its pivots 11 and such member can swing on the member 6 by its 7 such gear 29 is provided with circumferential grooves 29 therein to form the rack teeth 29 having the ,teeth 29 out upon the periphery of the same. The gear member 30 has the operating handle or rod 21" connected thereto and such gear has the long teeth 31 formed lengthwise of the same and the holes 32 cut into the metal between such teeth. In operation the gear teeth 31 of gear 30 work into the grooves 29 between the rack teeth 29' in the gear 29 and cause said gear to move longitudinally when gear member 30 is rotated by the operator through the rod 2 1" and may be moved in either direction, while the movement of the gear 30 longitudinally the teeth 29 of'gear 29 will engage the holes 32 in the gear 30 and the gear 29 will be rotated thereby .'so that the lamps A and their connecting parts can thus be shifted to either side or up or down by such movements, as shown, and through the medium of the rods 19, levers 21, arms 25" and rods 24 connected to said gears.

In Figs. 10 and 11, operating rods 24: are connected to gear 29 and gear 30 is connected to gear 29 for operating the two lamps A which are generally mounted on the standards a on each side of an automobile, and in such case the arm 25 on said rods is provided with a ball 20 at its end which works within a socket 20 on each of such lamps, so that by the same movements of said gears as previously described, the lamps and their connecting partscan be shifted to either side or up or down as shown.

If desired, as shown in Fig. 1 an ordinary universal ]oint 33 can be placed in the 'rod 24 beyond the bearing 23, so that the machine or car to throw his'light towardthe direction that-he wishes to turn or see before the car reaches such point, as well as in going down hill where the road or street has a curve leading down or 'up another hill the light can be thrown ahead, in order to see what is ahead or coming in either case and thereby avoid collisions or injuries. It will also be seen that my invention can be used in shifting lights .for a number of different purposes and such shifting can be -made to put the light straight or at any angle at any time desired, which can be done readily, conveniently and quickly and without any liability of any of the parts getting out of order or breaking, while. at the same time the device is positive in its movements, and can be operatedby any unskilled person. It will further be seen that my device will enable the lights to be shifted when desired to avoid the blinding effect to persons in a machine when two automobiles are coming toward each other, and such shifting will also enable the lights to Y be used for repairs to the automobiles on which the devices are used or upon other machines not using the same but which may need such lights to be thrown upon the same when adjacent for repairs, as well as for other purposes.
